从文件中读取输入

Question

so I'm a newbie at C++, and I've been poking around on the internet on how to do this, and so far I have this:

void includeFile(string name){
    ifstream ifs;
    ifs.open(name);
    string commands;
    while (getline(ifs,commands)){
        commandReader(ifs);
    }
    ifs.close();
}

(commandReader is a function that takes an istream)

When I try to compile, I get the error "no matching function for call" and then gives me the line number for the ifs.open(name) line. I've included fstream, so not sure why it's doing this

Answer 1

Sorry, never mind; found the answer right after I posted this. The solution was to have name.c_string() as the parameter instead, as string support was only added in c++11

Answer 2

As @chris pointed out, pre-C++11, ifs.open expects a char* , not an std::string . Try ifs.open(name.c_str()) .
